Method of cleaning
WARNING
- Before starting operation, make sure that compressed air is not supplied to the pump.
- Before starting operation, make sure that the pump is not pressurized.
1) Remove the hose from the suction side of the pump.
2) Close the flow valve on the discharge side, open the drain valve, and then operate a pump by
starting air pressure for a while to discharge any material remaining inside the pump as much as
possible.
3) Remove the hose from the discharge side, and attach different hoses to the suction side and the
discharge side for cleaning.
4) Remove the hose from the suction side of the pump, run the pump for a while and purge the pump
of remaining material as much as possible.
CAUTION
- Be careful when removing piping. Material will gush out.
- After cleaning by running the pump dry, hang the pump upside down to remove the residual
material.
- Using water or any other liquid to clean the pump may cause powder to absorb water and
stick to the inside of the pump, resulting in operation failure.
